WebCreate a 1-by-4 row vector, A, and a 4-by-1 column vector, B. A = [1 1 0 0]; B = [1; 2; 3; 4]; Multiply A times B. C = A*B C = 3 The result is a 1-by-1 scalar, also called the dot product or inner product of the vectors A and B. Alternatively, you can calculate the dot product A ⋅ B with the syntax dot (A,B). Multiply B times A. C = B*A http://www.matlab.enge.vt.edu/vectormath.html
Web20 apr. 2011 · This means that if f returns a scalar, x will be a scalar and if it returns a vector x will be a vector. In your example, this holds as long as t is also a scalar - otherwise the result will depend on how t* [output of f] is evaluated. Example function o1 = f (N) o1 = zeros (1,N); end Here f returns a scalar if N=1 and a vector for N>1.
